What does your work involve, and will it benefit from more cores/threads or is it light office work that doesn't push your components at all? PCPartPicker (Oz link since you mentioned ) is a great place to start for pricing and has decent compatibility filters that can provide a sanity check that you're matching components which will work together. In terms of gaming, what titles do you enjoy and what are your expectations in terms of graphical settings and framerates? 4k is a difficult resolution for AAA games at high detail for all but the highest end graphics cards, but if you're willing to sacrifice graphical fidelity and/or resolution you can get away with a much cheaper setup. If you're looking at 1080p gaming and you don't need the absolute highest of settings and highest of refresh rates then something like a 1060 6gb or an RX 580 could more than suffice. At 4k for high settings with decent framerates you're looking at something like a 1080/1080TI/2080/2080TI.

Head over to PCPartPicker, enter the specs you're looking for, and sort by price. (Link is setup for 27inch 144+hz 1080p monitors and sorted for price ascending but you can obviously adjust that. Default country is USA too so change that if you aren't!)

I have enough peripherals that need charging, don't care for another. Wired all the way

For gaming you will not see a significant difference as both single core and quad core speed are within approximately 5-10% of eachother. The big jump will be in multithreaded workloads so if you're doing plenty of video editing or other workstation tasks you will see a potential 2-3 factor decrease in rendering time.

Ram timing/clocking is generally performed through your BIOS/UEFI. This can be accessed by following these steps: 1) Click the Start Start menu and select Settings. 2) Select Update and Security. 3) Click Recovery. 4) Under Advanced startup, click Restart now. 5) The system will restart and show the Windows 10 boot menu. 6) Select Troubleshoot. 7) Choose Advanced options. Select UEFI Firmware Settings. Click Restart to restart the system and enter UEFI (BIOS). Every motherboard manufacturer has a slightly different interface so I can't provide you exact directions but you will need to enable what is called an "XMP Profile". It's usually quite obvious once you scroll through all the tabs and read all the lines. Don't stress about it! It's really rather simple, just take your time and read. Regarding dual channel vs single channel: You can check your motherboard manual which recommends if you have two DIMMS to install your memory in the B2 and A2 slots (the second closest to your CPU and the fourth closest to your CPU)[Page 21].

If you're using Ryzen you'll want fast memory which is essential for Infinity Fabric to aid the CPU in running as fast as possible. Samsung's B-Die RAM seems to be working the best with Ryzen and is the likeliest to run at 3200mhz+. Hynix M-die RAM is a slightly cheaper option and if you loosen the timings may get it running at 3200mhz+.

Can only comment on the AsRock b450 Pro4, but I'm running a 2600 on it as well. It's a good board so far and hasn't limited me in anyway. Currently overclocked to 4.1ghz fully stable on all 6 and could probably hit 4.2 if I had a better cooler. Frankly I don't see a reason to upgrade your mobo beyond an entry level b450 with your CPU especially if you don't plan on overclocking but I guess if someone else can chime in they should. Only negative really is the AsRock Polychrome RGB controller software which is hot trash, unless you want to set your components to static colours I'd avoid it.
